If you replaced the other drives then you would either need to fail/remove a drive, then add in the new 3tb drive and allow it to re-sync, then replicate 1 by 1 till all replaced then perform a grow... or build a new array from scratch. Having done a similar 1/1 replacement over a number of drives reciently, not without incident, I personally would go for a from scratch new build if I did it again saving both time and potential mistakes. > Cheers, > Mathias > -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
